Abstract
【解決手段】回路基板7の裏面側に配された導体パターン9Bの各小領域9B1〜9B5からは各々引出配線パターン10が伸びており、各引出配線パターン10は、途中でスルーホール11によって回路基板7の表面側に取り出される。表面側に取り出された各引出配線パターン10は、ジャンパパッド12を介して低圧側の端子部8に接続されている。ジャンパパッド12をハンダによってショート状態とすることにより、所望の小領域9B1〜9B5を機能させることが可能となる。各小領域9B1〜9B5は、機能させたときに、各々例えば1pFの容量を有するように構成され、パターンコンデンサ9としての容量は、ショート状態としたジャンパパッド12の数に比例した容量とされる。
【選択図】図1
Description
また、上述した2次側高圧ラインにコンデンサを付加する方策においては、コンデンサ端子と配線パターンの間でのハンダ付け不良を防止するために、手間と時間のかかる作業を強いられることになり、結果として生産速度の低下を招来する。
該インバータ回路のトランス2次側において、該放電灯の駆動に係る、共振周波数を決定する静電容量を、回路基板の対向する表裏領域に設けた導体パターンからなるパターンコンデンサにより形成し、
前記パターンコンデンサを構成する導体パターンのうち、表裏いずれか一方を、複数の領域に分割してなることを特徴とするものである。
該引出用配線パターンの途中には、微小間隔をあけて配線パターンが対向するジャンパパッドが設けられていることが好ましい。
トランスの2次巻線の一端側に接続される回路基板の対向する表裏領域に設けた導体パターンからなるパターンコンデンサを備え、
該パターンコンデンサの一方の該導体パターンは複数に分割され、該複数に分割された導体パターンの小領域の各々に接続され、ジャンパパッドをショートさせるか否かにより、該パターンコンデンサの静電容量を可変とすることを特徴とするものである。
本実施形態のインバータ回路は、放電灯(冷陰極放電ランプ:CCFL)を放電、点灯させるためのインバータトランスを搭載した放電灯駆動回路である。
すなわち、この駆動回路は、昇圧トランス22、トランジスタTRおよび駆動用IC23を用いて、放電灯21を駆動するものである。
C=ε×S/d (1)
ここで、
ε:誘電率
S:電極の面積
d:電極間の距離
したがって、このようにしてジャンパパッド12をハンダによってショート状態とすることにより、所望の小領域9B1〜9B5を機能させることが可能となる。
